WASTE BURNER AND INCINERATOR.

Specification of Letters Patent.

Application filed March 25, 1912.

bined waste burner and garbage incinerator,

intended particularly for domestic use and for meeting the conditions imposed for use in such manner. It 1s particularly intended i to provide a burner and incinerator which can be easlly used in con unction with a refuse box into which the ashes and debris from the burner and incinerator may fall.

Ditticulty has been encountered in incineratiug garbage and the like, the fact that the garbage has a tendency to cake or harden into a solid mass, which burns very slowly and cannot be easily broken up to insure its thorough consump tion.

One of the main objects of this invention is to provide a form of basket or cradle for I the garbage, such that the heat and gases from the fire can penetrate into the central part of the mass and thus carry on the disintegration and consumption of the garbage from its interior as well as its exterior. Atthe same time the device which serves to enable the heat and gases to thus penetrate into the central part of the mass serves also to prevent the garbage from collecting into a single mass which may harden and cake together.

Another object of the invention is to associate this basket or cradle with a chamber in which waste paper and the like can be burned so that the heat which would otherwise be wasted in burning such waste paper may be used for the purpose of consuming the garbage. Inthis manner a saving of fuel will be effected and a double result accomplished in the burning of waste paper, etc. Nevertheless, I associate a burner with the basket or cradle in such way that in case the amount of heat thus generated is insufficient the deficiency can be made up by additional fuel, in the form of gasolcne, briquets, etc. In each case, however, the basket or cradle is so formed that the heat will penetrate into the central part of the by reason of i garbage mass to accomplish the result first above mentioned.

Other objects and uses will appear from a detailed description of the invention, which consists in the features of construction and combinations of parts hereinafter described and claimed.

In the drawings: Figure 1 shows a perspective view of the burner and incinerator as the same may be associated with a waste receptacle; Fig. 2 shows a perspective view of the rear portion of the waste receptacle shown in Fig. 1; Fig. 3 is a vertical section through the upper portion of the receptacle and through the burner and incinerator; the basket or cradle and associated parts being shown in elevation, however; Fig. 4 is a cross section similar to that of Fig. 3; Fig. 5 is an enlarged plan view of the basketor cradle; and Fig. (3 is a cross section taken on line 06 of Fig. 5 looking in the direction of the arrows.

Referring now to the drawings, the burner and incinerator 7 is shown as associated with a waste receptacle 8, so that ashes and other debris from the burner will fall directly into the receptacle. For this purpose there are provided a number of slots 9 in the top of the receptacle, which register with the lower open end of the burner. The receptacle proper is provided with an outstanding portion 10 of box-like formation, adapted to project through a hole in a fence, the lower edge 11. of this projection being at proper elevation to just clear the rail 12 of the fence. A door 13 is hinged within the projection at approximately its mi(:l-portion, and is adapted to let down against a slanting portion 14 of the projection, so that when the door is lowered it will tightly close the opening 15 by reason of its weight. This opening is to permit the contents of the box to be removed therefrom at. the alley-side.

The burner and incinerator preferably made of concrete or other rock-like substance. By using this or like material it can be very easily molded and will possess tire-proof and other like desirable qualities for the present service.

The burner is open at its lower end and (mmprises side walls '16 and 17, a rear wall 18, and a front wall 1.). The upper portion of the burner is formed to provide a roof 20, having ventilating or smoke openings 21 and 22. An opening 23 is provided in the lower portion of the front wall, and an opening 24. near the upper portion thereof. The first of these openings is for the purpose of admitting waste paper, fuel and the like,

while the latter opening is for admitting. garbage or other matter to be lncinerated,

Doors 25 and 26 are provided for these openings. The lower edge of the front wall is cut away at the point 27 for purposes of draft, even when the door 25 is closed. Under ordinary circumstances, however, the burner will draw air up through the openings 9 from the waste receptacle, so as to insure that the latter will be well ventilated at all times.

The structure thus far, described has particular reference to the construction whereby waste paper and the like may be consumed. In'the central portion of the burner chamber a basket or cradle 28 is supported, the same being adapted to receive the matter to be incinerated. This basket or cradle preferably comprises an upper ring 29, a lower plate 30, and connecting bars 31. desired, all of these parts can be made integral, as, for example, by casting them from iron, but they are preferably divided on the line 32, as shown in Fig. 5, so that they can be more easily inserted within the burner chamber, The basket or cradle may be supported in any suitable way, but is preferably suspended from brackets or pins 33 carried by the walls of the burner chamber and adapted to support the upper ring 29 of the basket.

The bars 31 converge together in their lower ends and are placed close enough to hold the kind of material which is to be consumed by incineration. Under ordinary circumstances this material would pack into he lower part of the basket, so that the heat from matter being burned beneath the basket would not penetrate into the interior portion of the mass. In order to obviate this d'fliculty, I provide a flue 34C or the like,

in the central portion of the basket. This has its lower edge 35 supported some distance above the plate 30, for a purpose to be presently shown. The flue is also provided with a number of vertical slots 36. In the construction illustrated, the flue is supported by legs 37 which are secured to the plate 30.

Under ordinary circumstances, the heat from burning papers and the like will be sufficient to incinerate the garbage. When this is not the case, however, additional fuel, such as coal, wood, etc., may be used. To this end a gasolene burner 38 is supported slightly below the plate 30, having its perforations 39 extending out at such angle that the flame will clear the edge of the plate. The flame will then pass up through the lower portion of the basket, where it will strike the garbage. Therefore, the garbage and other matter will first. be consumed at such point. By reason of this fact, an opening Will soon be burned in through the lower portion of the mass of garbage, and presently a portion of the heat from the flame willbe deflected inward beneath the lower end of the flue, so that such heat can pass up through the flue and out through the slots 36 thereof to carry on the incineration from the interior of the garbage mass as. well as from its exterior. Of course, under any circumstances, a portion of the heat will simply pass up around theoutside of the garbage mass, so that. the incineration will be carried on from both the exterior and the interior.

A fuel tank 40 may be supported outside of: the chamber, a pipe a1 leading down from the same along one of the bars 31, and finding a connection with the burner 38 in its rear portion.

At times, it might be desired to supply the additional; amountv of; heat by fuel other. than gasolene or the like, for which purpose a rack 42 is provided, the same having, slotted side. walls 43, which, have their upper, ends 44: inturned a slight amount to grip the edges of the plate 30. This rack. ispreferably open at the front and rear, so that a briquet or the like can be slipped into it The heat from this through the. door 23, briquet will" act in; a manner very similar to that of the gasolene burner 38 for incinerating the garbage mass from both the exterior and the interior simultaneously.

From the above described construction, it will be seen that under any circumstances the ashes and unconsumed matter can fall directly from the burner and incinerator through the slots 9 'to the waste receptacle beneath. For this reason, the arrangement herein shown and described is an unusually satisfactory one, because it makes. it unnecessary to remove ashes and the like from the burner and incinerator after the burning operation is completed. At the same time the arrangement is such that natural draft created by the heat will draw upthrouglrthe waste receptacle beneath to keep the same thoroughly aired and in sanitary condition.
